SPECIFICATION forming part of Letters Patent No. 782,464, dated February 14, 1905.

Application filed May 11, 1904. Serial No. 207,388.

To mZZ w/wm it may concern:

Be it known that I, WALTER PERDUE, a citizen of the United States, residing at Winthrop, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Puzzles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to puzzles; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a side view of the device. Fig. 2 is a cross-section through the device.

.A is atube of glassor other transparent material which is closed at one end by a stopper of cement, b, or other suitable material. The other end, 0, of this tube is concavo-convex.

B is a shorttube of glass or other approved material, which is smaller in diameter than the tube A. One end of the tube B is inserted in the stopper 1) and is closed by the said stopper. The other end, 03, of the tube B is open, and the tube B is preferably arranged centrally of the tube A and parallel with it. The tube B projects within the tube A for about one-half of the length of the tube A.

C is a globule of mercury 0r quicksilver, which is placed inside the tube A.

The puzzle is to transfer the globule of mercury from the tube A to the tube B. When the tubes are held in the position shown in Fig. 1, the globule of mercury is at the end 0 of the tube A, and by a very dexterous jerk it can be tossed into the open end of the tube B.

What I claim is' In a puzzle, the combination, with a straight ,and cylindrical outer tube having a hemispherical closed end, and a stopper which closes the other end of the said tube; of an inner straight and cylindrical tube which projects from the said stopper concentric with the said outer tube and for substantially one-half of its internal space, and a globule of mercury in the said outertube. 4

In testimony whereof I aflix my signature in presence of two witnesses.

WALTER PEItDUE.
